Question

我正在尝试学习COBOL，以期（希望）为此次危机提供帮助。我正在使用IBM course，它需要VSCode中的“ IBM Zowe Open Editor”和“ Zowe Explorer”扩展。我花了很长时间为它设置JDK。我正在使用JDK1.8.0_251，就像要求configuration一样。我仍然收到一个错误消息，说“ cobol语言服务器在最近3天内崩溃了5次”，导致我的代码无法运行。这是COBOL语言服务器的输出：

更新：我想我需要访问z / OS大型机。我在IBM的Master the Mainframe程序中找到了如何获得免费访问权here，但是显然我需要添加z / OSMF软件（该软件只能为您提供3天的免费试用期）或称为Remote System Explorer API的东西。。我会继续调查...

Answer 1

该报告中的数据中心升级当时没有COBOL服务器系统。 COBOL服务器现在已启动。我建议使用Open Mainframe Project，OMP，松弛通道cobol-programming-course作为帮助。仅供参考-z / OSMF已安装且可运行。 COBOL课程系统，主机大型机学习系统大师，Zowe教程系统和ZTrial系统都是具有单独IP地址的独立z / OS。请输入系统的ID和IP地址，以确保我们保持同步。

与服务器的COBOL连接已在VSCode中关闭
